Abstract: Current communication networks are full of mobile devices that are capable of performing data transfers at high data rates or access high resolution video streams. For such requirements, in the data communications there is a permanent concern of wireless communications development to keep up with the wired communication networks. Because the 802.11n technology is not fast enough for increasingly more users willing games and online broadcasts, the 802.11ac technology was developed. This new IEEE standard, along with the future technology 802.11ad, is aiming to achieve a new level of performance, called VHT (Very High Throughput). The goal is to reach transfer rates (over 1Gbps for now) comparable to those establish in wired networks. This article is proposing a study over 802.11ac technology by exploring the performances of the specific MCS (Modulation and Coding Scheme) with a handy digitally modulated signals investigation method, CCDF (Complementary Cumulative Distribution Function).

Abstract: In this paper, we have emphasized the BER performance of dual polarized DWT aided MIMO SC-FDMA wireless communication system. The simulated system under investigation with 4 × 4 antenna configuration implements various types of channel coding( LDPC& Turbo) and signal detection (MMSE-SIC, BLUE, ZF & OSIC ) techniques. On considering transmission of secured voice frequency signal in a hostile fading channel under MATLAB based simulative study, it is observable that the simulated system shows satisfactory performance in retrieving transmitted audio signal under scenario of implementing Turbo channel coding, MMSE-SIC signal detection and 8-QAM digital modulation schemes.
